Rare and elusive denizen of Andean cloud forest; found at higher elevations than any other puffbird. Distinctive; note especially the stout, black bill bordered by white feathers, chestnut underparts, and red eye. Found inside forest, often near exposed earthen banks, which they favor as nesting sites. Remains motionless for extended periods before suddenly sallying out to catch an insect or other small animal. Typical song is a series of evenly spaced, mellow whistles that can be imitated.
